Bacteria Essay Examples

bacteria. On the other hand, in the settling unit (SU), the activated sludge flows and settles at its bottom. The sludge is then recycled from the SU to the bioreactor. The operational feasibility of the ASP is contended to depend on different limiting factors. Most of the models assumed only one substrate, or one microorganism, or one biochemical reaction limited the feasibility of the ASP. Although microbial death is considered in such models, however; there is no provision of entry of decay products into the recycled substrate pool. However, the operational feasibility of the ASP was considered to be limited by the presence of excess sludge. The disposal of such excess sludge could increase the...

bacteria. Milk is known to be a balanced diet in nature as it contains minerals, fats, nutrients, vitamins as well as carbohydrate. Protein casein which is present in the milk gives it a white color. Disaccharide lactose is the major carbohydrate available in the cream (Hassan et al., 2012). When milk is at room temperature, it undergoes natural souring that is brought about by the lactic acid that is produced by the fermentation of lactose through the help of the fermentative bacteria of the lactic acid. Accumulation of the acid in the milk lowers the pH of the cream thereby causing the casein protein to thicken as well as cradling into whey and curds. Consequently, the bacteria acquire nutrient...

bacteria break down organic material in the absence of oxygen or where there is insufficient supply. This breakdown often happens when biodegradable material trapped under ocean water begins to decay. Leakages in natural gas also contribute a mainly of the total methane emitted to the atmosphere annually. Masses of ice and methane usually in the ocean floors are also a significant source of methane. Commonly referred to as clathrates, they release the trapped methane whenever the sea temperatures rise above the melting point. With the current trend in general rise in global average temperatures, there is a high probability the intensity of such releases shall multiply shortly and worsen the situation...

bacterial spores have a long lifespan on earth due to its extreme endurance to radiations and other life-threatening conditions. Microorganisms would often survive wherever they are found. The diverse genetic lineage is a common feature that enhances their ability to exist under any conditions (Tazi Et al., 525). The metabolic diversity also changes based on the increased catalytic activity and amino acid accumulation. The use of heat shock proteins ensures that the extremophiles conserve their genes hence continued survival outside the earth (Harrison, Et al. 204). The metabolites are broken down to provide the energy required for the survival. Furthermore, the defensive mechanisms depend on the...

bacteria of some sort. It is imperative to ensure that the environment in which the patient is being treated is as hygienic as possible. As a nurse, I frequently use infection-control policies that can only be learned through evidence-based practice. Such include wearing protective clothing such as masks and gloves, regularly washing your hands and using barrier protections. Despite having some of the busiest schedules in a hospital roster, ignoring infection-control measures can be detrimental to the patient as well as other workers. Although following the routine was difficult at first, I quickly learned to adjust. I often used EBP when giving oxygen to patients with chronic obstructive pulmonary...

bacteria, and parasites (WHO, 2018). Cancer is partially a behavioral disease as the use of alcohol and tobacco, lack of physical activity, and unhealthy diet, are significant causes of cancer. The outlined triggers are the four known risk factors for noncommunicable diseases. Up to 50% of cancer cases can get prevented if risk factors are avoided (WHO, 2018). Also modification of risk factors can help lower the possibility of developing cancer. Tobacco use is the number one risk factor, responsible for 22% of all cancers (WHO, 2018). External cancer-causing risk factors depend on where one lives. Not all areas in the world have high levels of ultraviolet exposure and ionizing radiation. For that...

Bacteria were some of the first organisms on our planet. They have evolved over time resulting in a variety of bacteria that are in existence today. They can be classified into two categories namely; gram positive and gram negative. This classification depends on the differential staining process referred to as Gram stain. The Gram stain classifies bacteria with respect to their ability to hold the violet color whenever decolorized by an organic solvent such as ethanol. This differential cell wall structure is also critical in determining the kind of antibiotics that are effective against them. The Gram stain retention is dependent on the bacterial cell membrane (Chudobova et al., 2014). The...

bacteria, fungi, viruses, pollen, and spores. Fungi and bacteria are found in significant percentages both indoors and outdoors. Environmental contamination increase as the level of hygiene decreases. Bacteria show a high growth in numbers than the slow-growing fungi. Higher percentages of fungi are present indoors than outdoors (Yassin and Almouqatea, 2010). Inorganic pollutants cause microbial contamination indoors. Bacteria and fungi can be emitted by animals, wastebaskets, and plants. According to Hauser (1986), laboratory settings and procedures can be compromised by microorganisms. Controlled bacterial and fungal growth needs favorable conditions. Hypothesis Fungi exist in either unicellular...

bacteria, symptoms in this stage usually include, bloody diarrhoea, not passing urine, vomiting and mild fever. If the problem is not resolved, it may lead to hemolytic uremic syndrome with more severe symptoms. This particular strain of bacteria is virulent and arises from consumption of contaminated food items such as unpasteurized milk and undercooked meat. In this case, the child consumed ground meat, which was probably undercooked and may have caused the contamination. This type of bacteria produces a toxin known as ‘verotoxin’ which spreads to the kidneys causing the formation of blood clots in the kidney blood vessels, which leads to kidney damage and eventually failure (Karpman et al.,...
